Objective To study the association between high fat-low carbohydrate diet score and newly diagnosed type 2 diabetes in Chinese population.Methods Data about 20 717 subjects aged 45-59 years from the cross-sectional 2002 China National Nutrition and Health Survey were analyzed.High fat-low carbohydrate diet was scored according to the energy of carbohydrate,fat,and protein.Results Of the 20 717 subjects,1 332 were diagnosed with hyperglycemia and 662 were newly diagnosed with type 2 diabetes.Multivariate adjusted analysis showed that the highest score of type 2diabetes patients was 2.75 (95% Cl:2.09-3.61).The score of type 2 diabetes patients was 1.87 (95% Cl:1.35-2.58) after further adjustment for their socioeconomic status and physical activity.No significant difference was found in the odds ratio after further adjustment for BMl,blood pressure,lipid level,and energy intake.No evidence was observed for the relation between high fat-low carbohydrate-diet score in type 2 diabetes patients due to high family income,less education,physical activity,overweight,hypertension,high TG,or low HDL level.Conclusion High fat-low carbohydrate diets,far different from traditional Chinese diets,are associated with the high incidence of type 2 diabetes in Chinese population.

Objective To investigate the prevalence of nonalcoholic fatty liver disease (NAFLD) in different university categories and its association with lifestyle/dietary habits.Methods A cross-sectional study was carried out on 9 378 faculty members and staff who participated in an annual health checkup at three universities selected by random cluster sampling.Demographic,anthropometric,biochemical indices and abdominal ultrasound measurements were collected.A nested case-control study was conducted with 200 NAFLD cases and 200 controls matched by gender,age (±3years),and university.Results The overall prevalence of NAFLD was 10.3% (13.7% in males and 6.8% in females).The prevalence was significantly higher in the science and engineering university (22.1%) than in the comprehensive universities with (6.4%) and without (10.9%) medical colleges.Obesity/overweight,hyperlipidemia,diabetes mellitus,and family history of NAFLD were independently associated with higher risk of NAFLD,as were frequent consumption of desserts and salty/spicy foods.Using nutritional supplements was a protective factor against NAFLD.Intake of coarse cereals,potatoes,vegetables,fruits,and milk was significantly lower,and intake of red meat,viscera,candies and pastries,cooking oil,and total energy was significantly higher in participants with NAFLD than in controls.Conclusion Science and engineering university faculty and staff are key targets for NAFLD prevention.NAFLD is closely associated with age,gender,university type,metabolic diseases,and lifestyle/dietary habits.
